Target
-
FunctionComponent of cohesin complex, a complex required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The cohesin complex may also play a role in spindle pole assembly during mitosis.
-
Sequence similaritiesBelongs to the SCC3 family.
Contains 1 SCD (stromalin conservative) domain. -
Post-translational
modificationsPhosphorylated by PLK. The large dissociation of cohesin from chromosome arms during prophase is partly due to its phosphorylation. -
Cellular localizationNucleus. Chromosome. Chromosome > centromere. Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin probably because of phosphorylation by PLK, except at centromeres, where cohesin complexes remain. At anaphase, the RAD21 subunit of cohesin is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation. In germ cells, cohesin complex dissociates from chromatin at prophase I, and may be replaced by a meiosis-specific cohesin complex.

Immunoprecipitation - Anti-SA2 antibody - N-terminal (ab229681)SA2 was immunoprecipitated from HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) whole cell extract with 5 µg of ab229681. Western blot was performed from the immunoprecipitate using ab229681. Anti-Rabbit IgG was used as a secondary reagent.
Lane 1: Control IgG instead of ab227524 in HEK-293T whole cell extract.
Lane 2: ab229681 IP in HEK-293T whole cell extract.
